The government will this week announce its decision on whether to allow Bulgarians and Romanians the right to seek employment in the UK as of 1 January, the day of their accession to the EU, or whether to postpone the right for a transitional period.

We all know that more people than expected came to Britain when 10 other countries joined the EU two years ago. But in the main, this has been a positive experience. They have filled gaps in our job market, paid far more tax than they have received benefits, and given an extra boost to our economy.

Of course, there have been some problems too. A few struggle with their English which can obviously cause safety problems while large numbers of young men in particular locations can cause difficulties. Although most have not brought families, those that have tend to congregate in the same areas and are inclined to use the same (normally catholic) schools.

Unfortunately there have also been cases of unscrupulous employers who have exploited migrants by pressuring them to accept poor conditions and low wages. But as I have said recently on the blog, this is something the trade unions have been quick to realise. The TUC’s guide to employment rights for migrant workers is particularly useful and is available in several languages. It also puts the traditional workforce and new arrivals on the same side, defending their common rights.

In these circumstances, it would be a pity if the government were to cave in to the tabloid clamour and postpone the access of Romanians and Bulgarians to the UK labour market. Access has proven to bring considerably more benefits than disadvantages. A (relatively) small extension to two more countries won't change that equation.

But above all, the consequences of restricting access should be thought through. It would not stop Romanians and Bulgarians coming to Britain - they have that right anyway. It would simply stop them taking official employment. The likelihood is that many will take unofficial employment, unregistered, unregulated and unprotected. They will be wide open to abuse and exploitation. They will not contribute taxes. Any media kudos gained in the short term will quickly be lost when the press inevitably exposes illegal workers from Bulgaria and Romania. Far better that they be officially registered. It would minimise the problems and maximise the benefits.

In reality, this is not so much a Home Office matter as one for the DTI, the Dept of Work & Pensions and not to mention the Foreign Office for its EU repercussions. In other words the government must take a collective decision and not be bounced.
